The heliport docking system can include a plurality of helipads that can be autonomously transported from area-to-area to assist in the logistics of heliport management and control. The helipad system can include a surface on which a VTOL can land and a controller that can perform functions related to routing, maintenance, object detection, and transport, among others. The helipad system can releasably secure the VTOL to the helipad and transport the VTOL to different areas of the heliport system. The helipad system can also fuel the VTOL by providing, electricity, combustible fuel, or other suitable energy source, and perform a maintenance check of the VTOL and create maintenance crew of any VTOL irregularities.

BACKGROUND 1. Field of the Invention

The present disclosure is generally related to heliports adapted to provide take-off and landing areas for vertical take-off and landing aircraft (VTOL), and more specifically to a heliport including an autonomous VTOL helipad system for the fueling and transport of idle VTOLs.

2. Background of the Invention and Description of Related Art

A heliport is well known as an airport or landing place for helicopters. Traditional heliports provide designated landing areas for the take-off and landing of rotorcraft. These landing areas are typically stationary surfaces that are part of a larger structure. These heliports include infrastructure proximate the landing area, such as landing areas with gates where helicopters can “park” so that passengers can de-plane and cargo can be removed, as well as docking apparatus that facilitate service vehicles that engage the parked helicopter in-place to refuel and service the aircraft. During the time between helicopter take-off and landing, an occupied landing area in the heliport cannot be used by other helicopters, thereby limiting the number of helicopters that can be accommodated. In other instances, heliports can include large airfields so that landing areas are more plentiful, however these airfields require additional vehicles to transport passengers and cargo to distant locations, adding additional wait time to the process. The additional service and transport vehicles expend additional fuel in reaching their destination.

SUMMARY

The present disclosure teaches technical advantages as a heliport docking system including automated transport, fueling, maintenance, and logistical management of VTOLs. The heliport docking system can include a plurality of helipads that can be autonomously transported from area-to-area to assist in the logistics of heliport management and control. The helipad system can include a surface on which a VTOL can land and a controller that can perform functions related to routing, maintenance, object detection, and transport, among others. The helipad system can releasably secure the VTOL to the helipad and transport the VTOL to different areas of the heliport system. The helipad system can fuel the VTOL by providing, electricity, combustible fuel, or other suitable energy source, and perform a maintenance check of the VTOL and create maintenance crew of any VTOL irregularities. Although the preferred embodiment discloses a VTOL, any type of aircraft can utilize the heliport docking system.

A central heliport management system can oversee the logistics and operation of a plurality of helipad systems. The heliport management system can be communicatively linked with one or more helipad systems via wired or wireless communication protocols, including the helipad controller. The heliport management system preferably includes one or more servers that can include waypoint and navigation algorithms. The heliport management system can assign an aircraft to a specific helipad system, identifying the specific information of the aircraft, including the dimensions and weight of the aircraft, whether the aircraft includes any passengers, the system status of the aircraft, the fuel level of the aircraft, the flight itinerary and schedule of the aircraft, and any cargo held by the aircraft, among other types of aircraft information. The heliport management system can also identify location and status of a particular helipad system, including GPS coordinates, fuel level, and time to arrival, among other types of helipad system information.

Accordingly, one embodiment of the present disclosure includes a heliport docking system, comprising: a helipad, including a VTOL fueling mechanism configured to provide a VTOL with an energy source, and a VTOL maintenance device configured to obtain maintenance data from the VTOL; a helipad controller operably coupled to the helipad, including a helipad routing module adapted to determine a destination of the helipad and a route to the destination, a VTOL maintenance module adapted to receive the maintenance data from the VTOL maintenance device and generate an alert based upon the maintenance data, and a VTOL fueling module configured to control the amount of fuel delivered to the VTOL aircraft by the fueling mechanism; and a transport mechanism operably coupled to the helipad and the helipad controller and configured to transport the VTOL to the destination along the route. The helipad can further include a VTOL sensor configured to detect the presence of the VTOL proximate the helipad, a VTOL securing device configured to secure the VTOL to the helipad, and an obstacle sensor configured to detect objects proximate the helipad. The helipad controller can further include a VTOL securing module adapted to control the VTOL securing device.

Another embodiment of this disclosure includes a method for operating a heliport system, comprising: receiving a request from an aircraft to land at a heliport; requesting transport of a helipad to a landing area to receive the aircraft; securing the aircraft to the helipad after landing; and transporting the helipad with the secured aircraft to a destination area; fueling the aircraft during transport; receiving maintenance data from the aircraft during transport; and unloading the aircraft upon arrival at the destination area. The aircraft can be a VTOL, rotorcraft, airplane, drone, or other aircraft. The helipad can be transported along a chain track disposed in the ground, towed, self-propelled, or transported via other suitable mechanism. The fueling of the aircraft includes supplying the aircraft with fuel to power a combustion engine of the aircraft, supplying the aircraft with electricity to power an electric engine of the aircraft via a static electrical connection between the helipad and the aircraft, supplying the aircraft with electricity to power an electric engine of the aircraft via an inductive charge from the helipad to the aircraft, or other suitable energy source provision. The method can further comprise scanning for obstacles while transporting the helipad from the landing area to the destination area via a sensor on the helipad.

DETAILED DESCRIPTION

The preferred version of the inventions presented in the following written description and the various features and advantageous details thereof are explained more fully with reference to the non-limiting examples included in the accompanying drawings and as detailed in the description, which follows. Descriptions of well-known components have been omitted so to not unnecessarily obscure the principle features of the invention as described herein. The examples used in the following description are intended to facilitate an understanding of the ways in which the invention can be practiced and to further enable those skilled in the art to practice the invention. Accordingly, these examples should not be construed as limiting the scope of the claimed invention.

FIG. 1 is a schematic view of a heliport system, generally designated as 10, in accordance with an embodiment of the present disclosure. In the heliport system 10, a helipad system 100 can be transported between a number of different areas, such as a take-off and landing area 14, a loading and unloading area 16, and a maintenance area 18, and a command area 20, along a route 12. The route can be followed via a transport mechanism, such as a chain, track, tug, rail, or other mechanism. Other areas can include, cleaning areas and restocking areas, amongst others. Routes 12 can be created between each area to avoid wasted resources in transporting a vehicle to all areas. Alternatively, a route can be specified between a subset of predetermined areas most commonly used. In one embodiment, the route 12 on which the helipad system travels can be a track with which the helipad system 100 can interact. In another embodiment, the route 12 can be a flat surface on which the helipad system 100 can drive itself or on which it can be towed by another vehicle. Obstacle sensors help guide the helipad system 100 along the route. The obstacle sensors can emit and detect ultrasonic, acoustic, LIDAR, or RADAR signals, and can include other active and passive mechanisms for obstacle detection.

The heliport system 10 allows aircraft to land in one area, have its contents removed or replaced in another area, and be maintenanced in yet another area. In this way, aircraft can be cycled-off of a transport schedule to allow for cleaning, repair, restocking of supplies, or decommissioning. Advantageously, resources required for specific functions, such as passenger service, cargo management, and maintenance can be grouped in predetermined areas minimizing the need to replicate resources at disparate areas.

The helipad system 100 can accommodate the takeoff and landing of aircraft. The aircraft is preferably a vertical take-off and landing aircraft (VTOL), but can be a helicopter, airplane, drone, or other aircraft. Once the aircraft has landed on the helipad 100, the helipad 100 can secure the aircraft to the helipad 100 and transport the aircraft between the different areas 14, 16, and 18 of the system 10. In the preferred embodiment, the helipad system 100 can fuel the aircraft that it is transporting and perform a maintenance check as the helipad system 100 moves along the route 12. Alternatively, the helipad system 100 can fuel the aircraft that it is transporting and perform a maintenance check while the aircraft is parked on the helipad system 100.

In one exemplary embodiment, the take-off and landing area 14 can be an area in which the aircraft takes-off from and lands on the helipad system 100. This area 14 can also serve as an area in which passengers of the aircraft can get board and de-plane the aircraft. Once the aircraft lands on the helipad system 100 at the landing area 14, the helipad system 100 can secure the aircraft to the helipad system 100. Additionally, the helipad system 100 can initiate fueling the aircraft and performing a maintenance check of the aircraft at the landing area 14. The helipad system 100 can then determine the next area to which the aircraft should be transported.

In another exemplary embodiment, after passengers have boarded or de-planed the helipad system 100, the helipad system 100 can determine whether the aircraft next needs to go to the cargo loading and unloading area 16. Alternatively, the heliport management system 102 can determine whether the aircraft next needs to go to the cargo loading and unloading area 16 and can communicate the destinations area to the helipad system 100. The helipad system 100 can determine the best route 12 transport the aircraft to the cargo loading and unloading area 16. Alternatively, the heliport management system 102 can determine the best route 12 to take to transport the aircraft to the cargo loading and unloading area 16 and communicate the destination area route to the helipad system 100. The best route 12 can be determined by taking into account distance, traffic congestion, obstacle detection, and speed of the helipad system 100, among other factors. At the cargo loading and unloading area 16, any cargo carried by the aircraft can be unloaded, and any cargo can be loaded on to the aircraft that it needs to carry for its next flight. The helipad system 100 can then determine the next destination area that the aircraft needs to be taken to.

In another exemplary embodiment, after conducting a maintenance check initiated by the helipad system 100, the helipad system 100 can determine whether the aircraft requires maintenance to be performed prior to taking-off for its next flight. Accordingly, the helipad system 100 can determine that the aircraft next needs to go to the maintenance area 18. At the maintenance area, required maintenance for the aircraft, as indicated by the maintenance check performed by the helipad system 100, can be performed on the aircraft. Once it is determined by the helipad system 100 that the aircraft needs to go to the maintenance area 18, the helipad system can select the proper route 12 to get to the area 18. The helipad system 100 can then determine the next area that the aircraft needs to be taken to.

In another exemplary embodiment, after receiving maintenance at the maintenance area 18, the aircraft can then be delivered back to the take-off area 14. Once the helipad system 100 has determined that the aircraft needs to be delivered to the take-off area 14, the helipad system 100 or the heliport management system 102 can determine the best route 12 to the take-off area 14. Once at the take-off area 14, the passengers needing to board the aircraft for the next flight can board the aircraft. Once the aircraft is ready for take-off, the heliport management system 102 can direct the helipad system 100 to release the aircraft so that the aircraft can take-off from the helipad system 100. A route 12 can be connected between each destination area, so that the shortest route can be determined by the heliport management system 102 or the helipad system 100. Alternatively, a circuitous route can connect each destination area sequentially.

Referring to FIG. 2, there is shown a block diagram of the heliport docking system, in accordance with one embodiment of the present disclosure.

The helipad system 100 can comprise a helipad controller 120. The helipad controller 120 can be configured to control the operation of the helipad 110. The helipad controller can include a VTOL securing module 122, a helipad routing module 124, a VTOL fueling module 126, and a VTOL maintenance module 128. In one embodiment the controller 120 can control the modules 122, 124, 126, 128 based on the data collected by or the actions performed by the different sensors 112, 116, devices 114, 118, and mechanisms 115, 117 of the helipad 110. In one embodiment the controller 120 can receive input data from an outside source that directs the controller 120 on the next action the helipad 110 needs to take. For example, in this embodiment the controller can receive input data from a flight control tower of the heliport system 10. In another embodiment the controller 120 can receive input data from an operator of the helipad system 100.

In one embodiment, the VTOL securing module 122 can retrieve the data obtained by the VTOL sensor 112. If the data obtained by the VTOL sensor 112 indicates that a VTOL is present on the helipad 110, the securing module 122 can engage the VTOL securing device 114 to secure the VTOL to the helipad 110. The VTOL securing device 114 can be controlled by the VTOL securing module 122 or the heliport management system 102. In one embodiment the helipad controller 120 can give direction to the VTOL securing module 122 on whether the VTOL securing device 114 should be engaged or disengaged based on the input data received by the helipad controller 120.

Referring now to FIG. 2, there is shown a flow chart exemplifying control logic embodying features of a method for securing and fueling the VTOL via the helipad. The control logic can be implemented as an algorithm on a server, general-purpose computing platform or other suitable microprocessor-based system alone, or together with described components, devices, or systems. The control logic can leverage the ability of a computer platform to spawn multiple processes and threads by processing data simultaneously. The speed and efficiency of the control logic can be greatly improved by instantiating more than one process execute the method. However, one skilled in the art of programming will appreciate that use of a single processing thread may also be utilized and is within the scope of the present invention. The method begins at 202 where the VTOL lands on the helipad 110. The method then proceeds to 204.

At 204, the VTOL sensor 112 detects that the VTOL has landed on the helipad 110. In one embodiment, the sensor can transmit a signal and determine that an aircraft is present by receiving a reflection of a signal. In another embodiment, the sensor can come into contact with a portion of the aircraft and thereby determine that the aircraft is present. The method then proceeds to 206.

At 206, the VTOL securing module 122 directs the VTOL securing device 114 to engage the VTOL. In one embodiment, the VTOL securing module 122 can retrieve the data obtained by the VTOL sensor 112. If the data obtained by the VTOL sensor 112 indicates that a VTOL is present on the helipad 110, the securing module 122 can engage the VTOL securing device 114 to secure the VTOL to the helipad 110. The VTOL securing device 114 can be controlled by the VTOL securing module 122 or the heliport management system 102. In one embodiment the helipad controller 120 can give direction to the VTOL securing module 122 on whether the VTOL securing device 114 should be engaged or disengaged based on the input data received by the helipad controller 120. The VTOL securing module 122 can include mechanical, magnetic, or other suitable securing mechanism. The method then proceeds to step 208.

At 208, the VTOL fueling module 126 enables the fueling mechanism 117. In one exemplary embodiment, the VTOL fueling module 126 can control an actuator operably coupled to the fueling mechanism 117. In another exemplary embodiment, the VTOL fueling module 126 can engage in inductive charger operably coupled to the fueling mechanism 117. The method then proceeds to step 210.

At 210, the VTOL fueling mechanism 117 begins supplying fuel to the VTOL. The step then proceeds to 212.

At 212, the VTOL sends a fueling status that is received by the VTOL fueling module 117. The method then proceeds to 214.

At 214 the fueling module 126 determines if the fuel level of the VTOL is sufficiently full. If it is not, the method goes back to step 212. If the VTOL is sufficiently full of fuel the method continues to step 216.

At 216 the fueling module 126 disables the fueling mechanism 117 from the VTOL. The method then proceeds to step 218.

At step 218 the fueling of the VTOL is complete.

FIG. 4 is a flowchart of a method 300 of moving a helipad system 100 from a current area of a heliport system 10 to a destination area of the heliport system. The method begins at 302, where the helipad system is secured to an area of the heliport system 10. The method then proceeds to 303.

At 303, the helipad system 100 communicates to the VTOL that the helipad is secured to an area of the heliport system. The method then proceeds to 304.

At 304, the helipad routing module 124 enables the functionality of the obstacle sensor 116 and the transport mechanism 115. The method then proceeds to 306.

At 306, the routing module 124 determines the destination area that the helipad system 100 needs to move to within the heliport area 10. The method then proceeds to 308.

At 308, the helipad system 100 is released from the current area of the transport system 10. The method then proceeds to 310.

At 310 the helipad system 100 communicates to the VTOL that the helipad system 100 has been released from the current area. The method then proceeds to step 312.

At 312 the routing module 124 and transportation mechanism 115 begin to move the helipad system 100 to the destination area of the heliport system 10. The method then proceeds to 314.

At 314 the obstacle sensor 116 and routing module 124 determine if the helipad system 100 has encountered an obstacle along the route to the destination area.

In one embodiment the destination area can be the cargo loading/unloading area 16. In one embodiment the destination area can be the maintenance area 18. In one embodiment the destination area can be any other area of the heliport system 10. Alternatively, this step can be skipped if the destination area for the pad is the TO/L area. The method then proceeds to 428.

At 428 the helipad is secured to the destination area. The method then proceeds to 430.

At 430 the helipad sends a message to the VTOL saying the helipad is secured to the destination area. The method then proceeds to 432.

At 432 the helipad initiates fueling of the VTOL. In one embodiment the fueling is initiated by the VTOL fueling mechanism 117 and the VTOL fueling module 126. The method then proceeds to 434.

At 434 the helipad sends a message to the VTOL indicating the fueling status of the VTOL. The method then proceeds to 436.

At 436 the desired action of the destination area can be performed. In one embodiment the desired action is the loading or unloading of passengers from the VTOL. In one embodiment the desired action is the loading or unloading of cargo from the VTOL. In one embodiment the desired action is performing maintenance to the VTOL. The method then proceeds to 438.

At 438 the VTOL sends a message to the controller indicating the fueling status of the VTOL. The method then proceeds to 440.

At 440 the controller sends a message to the helipad to complete fueling of the VTOL. The method then proceeds to 442.

At 442 the helipad sends a message to the controller that fueling of the VTOL is complete. The method then proceeds to 444.

At 444 the controller sends a message to the helipad to move the helipad and VTOL to the TO/L area. The method then proceeds to 446.

At 446 the helipad is released from the destination area. The method then proceeds to 448.

At 448 the helipad moves to the TO/L area. The method then proceeds to 450.

At 450 the helipad sends a message to the controller saying that the helipad and VTOL have been moved to the TO/L area. The method then proceeds to 452.

At 452 the controller sends a message to the helipad saying to unsecure the VTOL from the helipad. The method then proceeds to 454.

At 454 the helipad sends a message to the controller saying that the VTOL has been unsecured from the helipad. The method then proceeds to 456.

At 456 the controller sends a message to the VTOL clearing the VTOL for take-off. The method then proceeds to 458.
